Speaking of this topic, kind of. The other night I was feeling like I had a cold coming on, so I decided to take a Benadryl. I was rather paranoid to take it since 15 minutes prior I took 1,000 mg's of Keppra and didn't want it to devour my stomach lining.
Long story short, I don't think I have slept that well in years! Not sure that is good or not, but I was out like a light for a good 8 hours straight.
